hz question

[audioholic 5,000+ posts]

Material in the 20hz region isn't meant to be heard anyway, its meant to be felt. Especially in HT.

Sub-30hz material is much more prevailent in HT than in audio. Unless you play movies in your car at very high volume, or enjoy bumping to the occasional subsonic sinewave, allowing your sub to start 'unloading' in the 30hz region (danger zone starts in low 20hz region) will work fine.

Ive never heard a subsonic filter called a rumble filter before. lol //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

The term comes from a time when you reproduced music by dragging a rock through a groove.//content.invisioncic.com/y282845/emoticons/naughty.gif.94359f346c0f1259df8038d60b41863e.gif

I am curious how you guys are hearing the notes like 7 Hz? Is that a speaker playing or some type of headset device?

I know a lot of people who think they can hear 10-15 Hz, but what they are actually hearing is just air rushing in and out of the port, harmonics (as already pointed out), and things rattling.

If you REALLY want to know if you can hear 10 Hz, you are going to have to be in a sound both, headphones sealed to your ear, and someone else running the test.

I can play 5 Hz in my truck loud enough that anyone in it would hear something. . . .

I am not saying you can't hear it, but I think a lot of people "think" they can hear that low, but they really can't.

I agree with you when it gets down to below 15 Hz. I believe that I can hear 18 Hz though.
